Summary
Pregnancy outcomes in women with artificial heart valves show similar perinatal results for mechanical and bioprosthetic valves. However, bioprosthetic valves were associated with higher maternal morbidity, while coumarin derivatives proved safe during pregnancy.
Area of Science:
- Cardiology
- Obstetrics and Gynecology
- Reproductive Medicine
Background:
- Artificial heart valves are crucial for managing valvular heart disease.
- Pregnancy in women with artificial heart valves presents unique challenges for both mother and fetus.
- Comparing outcomes between mechanical and bioprosthetic valves is essential for optimal patient management.
Purpose of the Study:
- To investigate pregnancy outcomes in women with artificial heart valves.
- To compare maternal and perinatal outcomes between mechanical and bioprosthetic artificial heart valves.
Main Methods:
- A retrospective analysis was conducted on 34 pregnancies in 29 women who conceived after cardiac valve replacement.
- Data on maternal and perinatal complications were collected and analyzed.
Main Results:
- Maternal mortality was 2.9%, with various morbidities reported, including heart failure and bleeding complications.
- The incidence of prematurity was 5.8%, and 11.7% of babies were small for gestational age.
- Maternal complications were more frequent with bioprosthetic valves, but more severe with mechanical valves; perinatal outcomes were similar between valve types.
Conclusions:
- Perinatal outcomes did not differ significantly between women with bioprosthetic and mechanical artificial heart valves.
- Maternal morbidity was higher in women with bioprosthetic valves.
- Coumarin derivatives were found to be safe and effective, without causing embryopathy.
